Definition of chlorophyll in English:

chlorophyll

noun ˈklɔːrəfɪlˈklɒrəfɪlˈklɔrəˌfɪl

mass noun

A green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.

Example sentencesExamples
- They also contain chlorophyll a, the same photosynthetic pigment that plants use.
- Important in this process are the green chlorophyll pigments in leaves which capture the sun's energy.
- Chlorella, a green algae, is rich in essential nutrients including chlorophyll, a useful blood purifier.
- However, some genepy has a greenish tint depending on the amount of chlorophyll in the plants.
- In higher plants, the pathways of chlorophyll and haem biosynthesis are tightly regulated at an early step.
- The green comes from chlorophyll, which allows the microscopic plants to get energy from the sun.
- In leaf tissue, the first outwardly visible signs of senescence are declining rates of photosynthesis and loss of chlorophyll.
- When the potato is green, chlorophyll and solanine levels dramatically increase.
- The ratio of soluble protein to chlorophyll in the isolated chloroplasts was approximately half that of whole leaf extracts.
- Greens are full of chlorophyll and one of the best healing foods we can eat raw.
- Most organisms with chlorophyll have additional pigments to capture more of the light energy that they receive.
- Early in the year, when there is plenty of light, the leaves produce chlorophyll, the green colour in grass stains.
- The chloroplast structure and the pigment assortment that includes chlorophyll a and c2, but not c1, suggest that only the red algae may be more primitive.
- Unlike plants, though, cyanobacteria lack a second kind of chlorophyll, known as chlorophyll b, which in concert with chlorophyll a helps plants capture light.
- The green colouring comes from chlorophyll, the same pigment that is found in foliage.
- Examples of the former are the green chlorophyll pigment in plant leaves and the orange pigment present in carrots, carotene.
- The efficiency of photosynthesis can readily be assessed by measuring chlorophyll a fluorescence of photosynthetic systems.
- Mushrooms do not have chlorophyll and cannot photosynthesize in the way that green plants do, to produce food.
- It is chlorophyll, specifically a kind called chlorophyll a, which transfers the energy absorbed from light to the molecules which go about storing it chemically.
- The chlorophyll captures the energy of light, and makes it accessible to the plant for photosynthesis.

Derivatives

chlorophyllous

adjectiveklɔːrəˈfɪləs

The foliose root is chlorophyllous, with extremely reduced vegetative and reproductive adventitious shoots scattered on the dorsal surface, and root hairs (adhesive hairs) on the ventral surface.
Example sentencesExamples
- Various hypotheses have been proposed to explain the reduced viability of chlorophyllous spores, including a higher respiratory rate or inability to recover photosynthetic competence after desiccation.
- Their roots cover rock surfaces, are chlorophyllous and have extremely short, leafy and floral shoots scattered on their dorsal surface; they play major roles in adherence, photosynthesis, organogenesis and reproduction.
- Along the abaxial and adaxial margins of the leaf the subepidermal vascular bundles are interspersed with fibre bundles in the chlorophyllous mesophyll.
- In a previous study, we suggested that once Coffea somatic embryos have developed chlorophyllous cotyledons exhibiting active photosynthesis, they could be successfully cultured photoautotrophically.

Origin

Early 19th century: coined in French from Greek khlōros 'green' + phullon 'leaf'.

Definition of chlorophyll in US English:

chlorophyll

nounˈklôrəˌfilˈklɔrəˌfɪl

A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
